DISCUSSION
NEXT 7 DAYS...
FRIDAY WILL SEE WARM AND MOSTLY DRY CONDITIONS UNDER AN UPPER
LEVEL RIDGE.
LOOKING AHEAD TO SATURDAY THERE IS ANOTHER CHANCE FOR
SEVERE WEATHER IN EASTERN MONTANA AS AN EVEN MORE POTENT
SHORTWAVE TROUGH MOVES THROUGH THE NORTHERN ROCKIES. THE SE
SURFACE FLOW WILL KEEP RETURN MOISTURE FLOWING IN ADDITION TO GOOD
OVERALL THETA-E ADVECTION KEEPING THE ATMOSPHERE READY TO KICK
OFF STORMS. AS THE FORCING APPROACHES DURING THE DAY SATURDAY
TEMPERATURES ARE ALSO FORECAST TO BE ABOVE AVERAGE WHICH SHOULD
AID IN RAISING SB CAPE VALUES. CLOUD COVER SHOULD BE LESS OF A
PROBLEM SATURDAY AS WELL DUE TO A WEAK RIDGE THAT BUILDS IN
TOMORROW AND THUS THERE SHOULD BE MINIMAL LINGERING CLOUDS
SATURDAY MORNING. LARGE HAIL AND DAMAGING WINDS WILL BE THE MAIN
THREAT SATURDAY AS THE WIDESPREAD HOT TEMPERATURES SHOULD RAISE
THE LCL ENOUGH TO KEEP TORNADOES A NULL THREAT, EVEN WITH A NICELY
HUMPED HODOGRAPH.
NEXT WEEK IT LOOKS LIKE THE PATTERN REMAINS ACTIVE WITH SEVERAL
MORE ROUNDS OF ENERGY MOVING ASHORE OFF OF THE NORTHERN PACIFIC.
DETAILS REMAIN FUZZY THIS FAR OUT SO BE SURE TO CHECK THE FORECAST
AS WE GET CLOSER AS THINGS COME INTO BETTER FOCUS. WMR/ARCHER
